Care

Plant your bulbs in the fall to ensure they establish roots before winter. Watch for yellowing foliage after blooming, which is a sign the plant is storing energy for next year. Avoid overwatering during their summer dormancy to prevent bulb rot.

Watering: Keep the soil consistently moist during the active growing season but allow it to dry out once the foliage dies back.
Feeding: Apply a balanced bulb fertilizer once in the early spring as new growth emerges.
Pruning: Remove spent flower stalks after blooming, but leave the foliage until it turns yellow so the bulb can recharge.
Repotting: Divide and repot clumps every few years if they become too crowded or if flowering performance declines.

Temperature: -25 to 30°C

Growing it

Propagation: division, seed
When to plant: autumn
Overwintering: No special care is needed as the bulbs are hardy and remain dormant underground during the winter months.
In containers: They grow very well in pots, provided the container has good drainage and is at least 15 cm deep.

Division

Wait until the foliage has yellowed in late spring or early summer.
Carefully dig up the clump of bulbs.
Gently separate the smaller offsets from the main bulb.
Replant the offsets immediately at the same depth they were previously growing.

Plant these in groups of at least ten to create a significant visual impact in the garden.

Grows well with

Daffodil · They bloom at the same time and provide a lovely color contrast.
Tulip · The blue flowers of the grape hyacinth look great against taller tulips.
